Ngokusebenzisa uhlalutyo lweempawu ze-parasitic ze-vias, sinokubona ukuba kwisantya esiphezulu PCB uyilo, ii-vias ezibonakala zilula zihlala zizisa iziphumo ezingalunganga kuyilo lwesekethe. Ukuze kuncitshiswe iziphumo ezibi ezibangelwa yimpembelelo ye-parasitic ye-vias, oku kulandelayo kunokwenziwa kuyilo:

1. Ukuqwalasela ixabiso kunye nomgangatho wesignali, khetha ubungakanani obufanelekileyo ngesayizi. Umzekelo, kuyilo lwemodyuli ye-6-10 yememori ye-PCB, kungcono ukusebenzisa i-10/20Mil (i-drilled/pad) vias. Kwezinye iibhodi ezinoxinano oluphezulu ezinobungakanani obuncinci, unokuzama ukusebenzisa i-8/18Mil. umngxuma. Phantsi kweemeko zobugcisa zangoku, kunzima ukusebenzisa ii-vias ezincinci. Ngamandla okanye nge-vias yomhlaba, unokucinga ukusebenzisa ubungakanani obukhulu ukunciphisa i-impedance.

2. Ezi fomyula zimbini zixoxwe ngasentla zinokugqitywa ukuba ukusebenzisa i-PCB encinci kunenzuzo ekunciphiseni iiparamitha ezimbini zeparasitic ye-via.

3. Zama ukuba ungatshintshi iileya zeempawu zomqondiso kwibhodi ye-PCB, oko kukuthi, zama ukungasebenzisi ii-vias ezingeyomfuneko.

4. Amandla kunye nezikhonkwane zomhlaba kufuneka ziqhutywe kufuphi, kwaye ukukhokela phakathi kwe-via kunye nepini kufuneka kube mfutshane njengoko kunokwenzeka, kuba baya kwandisa i-inductance. Kwangaxeshanye, amandla kunye nezikhokelo zomhlaba kufuneka zibe ngqindilili kangangoko ukunciphisa impedans.

5. Beka ezinye ii-vias ezisekelwe kufuphi ne-vias yomgca wesignali ukubonelela nge-loop ekufutshane yomqondiso. Kuyenzeka nokuba ubeke inani elikhulu le-vias engafunekiyo emhlabeni kwibhodi yePCB. Ngokuqinisekileyo, uyilo kufuneka lube bhetyebhetye. Imodeli ekuxoxwe ngayo ngaphambili yimeko apho kukho iipads kumaleko ngamnye. Ngamanye amaxesha, sinokunciphisa okanye sisuse iipads zezinye iileya. Ngokukodwa xa ukuxinana kwe-vias kuphezulu kakhulu, kunokukhokelela ekwakhiweni kwe-groove yekhefu eyahlula i-loop kumaleko wobhedu. Ukusombulula le ngxaki, ukongeza ekuhambiseni indawo ye-via, sinokucinga ngokubeka i-via kumaleko obhedu. Ubungakanani bepadi buncitshisiwe.
